I received my Genesis 3.1 a couple of week ago and have had it out a few times now. This is my first DPV so I am not qualified to give a very detailed review, but since there are so few reviews out there at the moment, I'll at least share my impressions.

The DPV is impeccably engineered and assembled. I'm a EE myself and have put many products into production over the years, and I am very impressed with the electrical and mechanical design of this DPV. The ability to charge without disassembly is great of course, but the design goes way beyond that feature and is almost what I would call military grade. It certainly provides a good feeling when taking the DPV into the open ocean.

Ride-wise, the DPV provides an extremely smooth start-up and it requires almost no support on the handle. All of the pulling load is on the tow line and your hand really just provides input for throttle and steering. It's very comfortable at a typical cruising speed. Mine is still a bit nose-light, so I need to add a little trim to the nosecone, but even in that state it handles very well.

I purchased the DPV for debris removal operations, both for shore-launched dives and from a boat, diving to near-shore areas, mostly heavy fishing areas with lots of fishing line. So far I have only used it on short runs of perhaps 1 mile total, and after several dives I still have a nearly-full battery according to the battery gauge. It's unlikely I will ever use the full range of this beast but at times I will be towing either gear or another diver so that may challenge the battery a little bit.

Noise-wise the Genesis seems very quiet to me. DPVs are common where I dive and usually I can hear the high-pitched whine from some distance, but I don't hear that whine from the Genesis. I'm not running it at full speed though so maybe at the highest speeds it starts to whine. At the lower speeds it is very quiet.

If anyone has any questions please ask. Overall I think it is a great DPV. Not the cheapest of course but for mission-critical use I think it is a great option.
 
Thank you for your review. Enjoyed reading it.
 
Hi Rick, Good "preliminary" review. Thank you.
I too am now considering a 3.1. Can you send a few close up pictures of the handle area, couple of different angles? Logic's website only has few pics showing the overall unit. I'm just curious how the triggers work, this variable speed concept - how that works with left or right hand. That type of thing.
 
I'm not with my Genesis at the moment but next time I am I can send a few. There are a couple other owners here also, maybe they can help out sooner. The trigger itself is a plastic bar that is spring-loaded and pulls in to "go". It is a simple on/off. The speed setting is a small plastic lever that is in the same general area and it rotates to adjust the speed. I believe when using right-handed you can tweak the speed with your thumb. I don't adjust it much myself, turning it to kind of the sweet spot speed and leaving it there. I'm going on memory here though.

Rotary speed controller in the blue circle, currently in the 6 o'clock "off" position. Rotate upwards with your right thumb for more speed, pointing vertically upwards at 12 o'clock is 100% power. Typical driving speed is in the 2 o'clock to 4 o'clock range. Full power is incredibly uncomfortable unless you are towing someone.

Trigger is the PVC bar to the left of the green arrow, grip with fingers to activate. Only on/off no other functionality (no mouse clicks, no motorcycle grip action)

Trigger lock (can lock on or off) below the orange arrow. Rotate the aluminum plate to hold on the trigger in or away from the handle

I believe @Jon Nellis is willing to build units with a mirrored trigger for left handed folks.

This really helped me understand how the handle functions. Appreciate it. Forget my “left / right “ comment. I didn’t realize the handle was centered.
 
In my experience when needing to drive left handed you can put your left on either the upright, or just tuck your thumb under the upper tow line mount. The scooter really takes very little pressure to drive.
 
Is there an LED display for the 3.1? The internet and also John's site and also utube -I just can't seem to locate any images showing the display.

Also, when driving with left hand only by grabbing the left upright the way you describe...how does one operate the on trigger?
 
New to the Genesis 3.0, you'll notice a flashing LED in the window on the rear of the handle, that gives a visual indicator of battery charge. The flashes are relevant when the motor in not running (resting voltage), as the motor causes the battery voltage to decrease (sag) when running, depending on the speed. Levels are approximate, since they are voltage based.

5 Flashes = 5/6 or more charge remaining
4 Flashes = 2/3 or more charge remaining
3 Flashes = 1/2 or more charge remaining
2 Flashes = 1/3 or more charge remaining
1 Flashes = 1/6 or more charge remaining
Continuous Flashing = You have entered the power reduction charge level.
Solid ON = Motor fault.

After 30 minutes, the LED will blink continuous, just to get your attention, in case you forgot to remove the nose plug after you have finished diving. If you pull the trigger and run the motor, it will revert to reporting battery charge level.

Also new is the USB connector on the tail. There is a configuration app on our website, so users can adjust certain settings and load firmware changes, if needed. (MS Windows only) You will be able to change the voltage levels, power reduction levels (2) and RPM limits, LED brightness and speed control levels and a couple other things.

Most people dive the Genesis with the trigger locked ON and use the speed lever to stop the motor when needed, keeping a hand on the handle for control. If you need to take your hands off the handle, then you unlock the trigger. lock it OFF and also set the speed lever to OFF. If you want to swap between right and left hands while running, the trigger being locked ON makes it easy to swap hands and not stop the motor. You just need grab the handle or mounting arch to control the speed knob. Left handed, I control the speed with my pinky finger, others grad the left side of the arch and use their thumb. It's pretty intuitive once you are behind it.

Thanks for that Jon. This makes sense to me now.
